[njoubert-cleverage]

Description

Fixes #87. Demo processes for cleverage/process-bundle#307 (one file per process in config/packages/process/, expected output in each help):

Process	Shows	Output
demo.blocking.two_blocking_children	an iterable task with two blocking children: both proceeded once	first: [1,2,3], second: [1,2,3]
demo.blocking.no_direct_iterable_ancestor	blocking tasks after a non-iterable task, and without any iterable ancestor: proceeded	indirect: ["item 1","item 2","item 3"], no iterable: ["constant"]
demo.blocking.two_iterable_ancestors	a blocking task with two direct iterable ancestors: proceeded once	both: [1,2,3,4]
demo.input_aggregator.iterable	input_aggregator joins the two branches for each item	{"a":"a1","b":"b1"}, {"a":"a2","b":"b2"}, {"a":"a3","b":"b3"}
demo.input_aggregator.skipped_branch	bug cleverage/process-bundle#307: a branch skips an item, the inputs of two items are joined	{"a":"a1","b":"b1"}, {"b":"b2","a":"a3"}, {"b":"b3","a":"a4"}, {"a":"a5","b":"b5"} (expected: items 1, 3 and 5 only)

The tasks are referenced by their service (service: '@…'), like the other demo processes: the task key is unknown to process-bundle 5.3 (composer.lock), the migration is #84.

Checked in the container with process-bundle v5.3 and main (a32602b): same outputs, the 5 processes succeed.

Breaking changes

None: new demo processes.
